The caramel macchiato in 24mg I got from DFW Vapor was instantly something you'd have to pry out of my cold, dead hands for me to give up. I'm guessing they make their own juice(?) because that's the only thing it says on the label aside from the flavor/nic level.
It's caramel/vanilla sweet at the inhale, rich coffee and caramel on the tongue, and espresso tasting upon exhale. I love it. I have other juices, but haven't touched them since leaving the store in favor of this. Only since Tuesday evening though, so it's not exactly a long established love affair. No interest in changing it yet though!
